When you're in the mood, it's a sure bet that the last thing on your mind is boosting your immune system or maintaining a healthy weight. Yet good sex offers those health benefits and more. That's a surprise to many people, says Joy Davidson, PhD, a New York psychologist and sex therapist. "Of course, sex is everywhere in the media," she says. "But the idea that we are vital, sexual creatures is still looked at in some cases with disgust or in other cases a bit of embarrassment. So to really take a look at how our sexuality adds to our life and enhances our life and our health, both physical and psychological, is eye-opening for many people."

Sex does a body good in a number of ways, according to Davidson and other experts. The benefits aren't just anecdotal or hearsay -- each of these health benefits of sex is backed by scientific scrutiny.

Sex Relieves Stress

A big health benefit of sex is lower blood pressure and overall stress reduction, according to researchers from Scotland who reported their findings in the journal Biological Psychology. They studied 24 women and 22 men who kept records of their sexual activity. Then the researchers subjected them to stressful situations -- such as speaking in public and doing verbal arithmetic -- and noted their blood pressure response to stress. Those who had intercourse had better responses to stress than those who engaged in other sexual behaviors or abstained.

Sex Lowers Blood Pressure

Another study published in Biological Psychology found that frequent intercourse was associated with lower diastolic blood pressure (the lower, or second, number in a blood pressure reading). This study focused on people living with their sex partner.

Still further research found a link between partner hugs and lower blood pressure in women.

Sex Boosts Immunity

Good sexual health may mean better physical health. Having sex once or twice a week has been linked with higher levels of an antibody called immunoglobulin A or IgA, which can protect you from getting colds and other infections. Scientists at Wilkes University in Wilkes-Barre, Pa., took samples of saliva, which contain IgA, from 112 college students who reported the frequency of sex they had.

Those in the "frequent" group -- once or twice a week -- had higher levels of IgA than those in the other three groups -- who reported being abstinent, having sex less than once a week, or having it very often, three or more times weekly.

Sex Burns Calories

Thirty minutes of sex burns 85 calories or more. It may not sound like much, but it adds up: 42 half-hour sessions will burn 3,570 calories, more than enough to lose a pound. The number of calories burned during sex is about the same as the number burned by walking at 2 miles per hour.

Doubling up on the 30 minute sessions, you could drop that pound in 21 hour-long sessions.

Sex Improves Cardiovascular Health

While some older folks may worry that the efforts expended during sex could cause a stroke, that's not so, according to researchers from England. In a study published in the Journal of Epidemiology and Community Health, scientists found that the frequency of sex was not associated with stroke in the 914 men they followed for 20 years.

And the heart health benefits of sex don't end there. The researchers also found that having sex twice or more a week reduced the risk of fatal heart attack by half for the men, compared with those who had sex less than once a month.

Sex Reduces Prostate Cancer Risk

Frequent ejaculations, especially in 20-something men, may reduce the risk of prostate cancer later in life, Australian researchers reported in the British Journal of Urology International. When they followed men diagnosed with prostate cancer and those without, they found no association of prostate cancer with the number of sexual partners as the men reached their 30s, 40s, and 50s.

But they found men who had five or more ejaculations weekly while in their 20s reduced their risk of getting prostate cancer later by a third.

Another study, reported in the Journal of the American Medical Association, found that frequent ejaculations, 21 or more a month, were linked to lower prostate cancer risk in older men, as well, compared with less frequent ejaculations of four to seven monthly.

This suggests that sex is a medicine on it's own. I remember reading similar article few years back.

for sure it is if done with the right partner and in a good way too.

Which one is right partner again?
@topic
I agree with your article, is right to the point.

right partner. Legally bound

I remember reading similar article.
I think is educative, but religious folks tend to have different opinion when it comes to sex irrespective of scientific fact.
Now which one would people accept as important means, religion or health advice?

Its a good post, but having sex should be done normally with rightful partner. Not just haaving sex with someone without knowing his or her health situation
